Ever since Fort Sensible arrived as first prize in the Whacking Day, there have been reports of an unusual glitch that is likely to have an impact on anyone redesigning their town. Many people have reported that after putting one of the prize buildings in their Inventory, it needs another 24 hours to rebuild when they put it back into their Springfield.

This doesn’t seem to be a general glitch, however (I just tried storing and replacing my Fort Sensible and it didn’t need a rebuild). But, just in case it’s one that affects your game, my suggestion would be to exercise caution in placing the prize buildings in your Inventory – try it with one and see what happens when you take it out. If it looks like you need to rebuild your prize buildings, make sure you avoid the Inventory and, instead, place them in a temporary location in your town while you’re doing a redesign.
